IBM 3534 Fibre Channel Hub Model 1RU

This section gives troubleshooting information for the IBM 3534 Fibre Channel Hub
Model 1RU.
Each hub port includes an LED indicator. If a problem has been detected with the
port, the LED indicators provide some indication of the type of problem. Faults and
problems are displayed with a yellow port indicator. The color and blink speed of
each port's LED, as described in Table 18, indicates the status of each port.
If a GBIC is not installed, no light shows on the LED. When a GBIC is installed and
a cable is connected to a properly functioning Fibre Channel device, the LED
menu. Remove the CD, then restart the engine.
